I bought a Burley Nasoke. Since Burley has quit building bicycles (trailers only, now), a lot of dealers have discounted their remaining bicycles. I bought mine from Calhoun Cycle over the internet, and I had a bad experience with their customer service. (Nobody took responsibility for assembling or shipping the bike. Telling, eh?)
Anyways, the Nasoke is a LWB bike with a shock absorber. The ride is very smooth, very relaxed. I replaced and upgraded components, because I like tuning a bike for me and I'm mechanically inclined.
When I first got the bike and got it assembled, I found that I had to relearn how to ride a bicycle. I spent about a half hour just riding it around the block, getting the hang of it. Then I rode a few miles a few days later, and I did much better. This past weekend was my first 20-mile jaunt, and while I was a bit tired, I wasn't dead from it. The hardest part of the ride was learning to simply relax in the seat and just pedal.
When you buy a bicycle, you are basically buying a frame. If you own the bike long enough, nearly everything gets replaced at some point. My Giant Sedona has only a handful of original components on it. The Nasoke has a good base design, but Burley really should sell their stuff like Surly does: frame only.
The time to figure out if a bike "fits" you takes about an hour (at least) of riding. Pay attention to how you feel after riding it, and note anything minor.
My Nasoke currently has a Tubus Cargo rack, and due to the Tubus mounting accessories I mounted it without using the Burley rack adapter kit. I have changed the deraileurs, brakes, sprockets, wheels, handlebar, shifters, and I may change forks and steering components later.
